Vodacom Cancelled The incorrect contract

<p>I called vodacom for a Cancellation in April (I believe) and Instead of doing so, they cancelled one of my other contracts.</p> <p> </p> <p>When I ask for a refund for all the money I hhave been charged, Vodacom says it was my responsibility to tell them they messed up. As a result I am liable.</p> <p> </p> <p>Im not sure what the consumer protection act thinks about this but I want to be refunded.</p>
